PITTSBURGH, PENNSYLVANIA, ASSIGNOR TO MCKINNEY MANUFACTURING COMPANY, OF PITTSBURGH, PENNSYLVANIA, A CORPORATION PENNSYLVANIA LOCK AND LATCH I Application filed October 14, 1929. SerialNo. 399,528.

My invention relates to lock and latch structures, and more particularly to means for anchoring or holdin lock and latch casings in position upon a oor.

6 One object of my invention is to provide anchoring mechanism for lock and latch housings that can be conveniently applied and which will be effective to securely hold a housing in position within a door Another object of my invention is to provide holding means of the character described which will rigidly hold a housing or casing against displacement in directions parallel to the plane of the door, but which will per- 'mit of adjustments of the housing transversely of such plane.

Still another object of my invention is to simplify and improve generally the mounting in doors of latch and lock housings. The invention is shown in the drawings as employed in connection with a latchvstructure of the general type of that disclosed in Patent No. 1,720,636, issued July 9, 1929, to

W. E. Wread, but is capable of use also in connection with various other forms of latch and lock structures. 7

One manner in which my invention may be practised is shown in the accompanying drawings wherein Figure 1 is a side elevationalview of a portion of a door, showing the latch structure in place; Fig. 2 is a sectional view of the structure of Fig. 1, looking from the front thereof; Fig. 3 is a sectional view taken in the plane of the door, and Fig. 4 is an end elevational view of the latch housing. The latch housing consists of a cylindrical shell-like portion 6 and end plates 7 and 8. The end plates have tongue-like portions 9 that extend into recesses in the ends of the shell 6, to prevent relative rotative movement of the end plates and the shell. Each of the end plates 7 and 8 is provided with a hub-like extension 10 that is exteriorly threaded adjacent to its outer end. A bearing 11 extends through each of the hubs '10 and has a spindle portion 12. An inner knob 13 is secured to one of the spindles 12 and an outer knob 14 to the other spindle.

The inner ends of the spindles 12 carrlz discs 15, each of which has a cam or roll-bac portion 16 for retracting a cross head 17 upon rotation of either of the lmobs, as set forth in said patent. The cross head 17 is urged forwardly by a spring 18 and has a latch bolt carrier 19 that extends through the forward side of the shell 6. A latch bolt 20 has screw-threaded connection with the carrier 19.

Various other forms of latch or lock mechanism maybe substituted for the operating parts just described, as such parts in themselves do not constitute a feature of the present invention.

. The plates 7 and 8 are held in interlocking engagement with the shell 6 by means of screws 22, the plates being easily removable to permit insertion of the retracting mechanism into the housing. 7

In order to fasten the housingto 'the door, I provide clamping or anchoring plates 24 and 25. Clamping screws 26 and 27 extend through the plate 24 and loosely through holes in the end plates 7 and 8. These screws have threaded engagement with the plate 25 so that the plates 24 and 25 may be drawn into tight engagement with the sides of the door. Since the screws 26 and 27 extend through the end plates, the housing 6 can have no movement relative to the plates 24 and 25 in directions parallel to the plane of the door, but the housing may be slid longi tudinally of these screws or bolts, which serve as guide rods, to permit lateral adjustment thereof within the door so that the bolt carrier .19 can be positioned at any desired point between the sides of the door.

When the latch housing has been positioned laterally of the door, it is maintained in such position by means of finish plates 28 and nuts 29 threaded over the respective hubs 10. The finish or face plates 28 serve to conceal the end plates 24 and 25 and the clamping screws 26 and 27. The nuts 29 are screwed up against the plates 28 to hold them in clamping engagement with the sides of the door. The latch housing is thereby held against displacement transversely of the door and at any desired position of adjustment with respect to the plane of the door. a f

The screws26 and 27 are shown-as extend.-

ing from the inside of the door to the outer side thereof, so that if the outer nut 29 and the face plate 28 be removed, the screws 26 and 27 cannot be manipulated from the outside of the door, thus preventing disassembly of the mechanism from the outside by an unauthorized person.

lVhile I have shown and described a present preferred embodiment of the invention, it is to be distinctly understood that the same is not limited thereto, but may be otherwise variously embodied within the scope of the following claims.
